This set is a limited edition due to the pattern cut from large material to duplicate this set. This set as seen was ordered at 8mm for his and 2mm for hers polished. Hers is a polished inside and his isn't, showing off the pattern through to the inside. In the note to seller please list the sizes. Also His can be from 7mm-9mm wide and hers 2mm-4mm. Thank you, Josh
